Description
  • Gypsum is very old material but in the recent time iťs importance is growing with the increasing amount of gypsum from flue gas desulphurisation (FDG). The application properties of natural and FDG gypsum are possible to improve by adding of appropriate ingredients. Some possibilities how to improve the consistency and the strength of the gypsum were tested. Also the best formulation of the foamed gypsum products was tested. These additives were tested: plasticizers, dispersions and several types of fibres. As foaming agents for preparing of foamed gypsum was used chalk with some acid components. All the tested additives are commercionally available products in powder form. The powder form was chosen because it enables to formulate dry gypsum mixtures ready for preparing of gypsum products on the construction site.

  • Sádra je velmi starý materiál, v současné době však její význam opět vzrostl se stoupajícím množstvím sádry z odsiřování tepelných elektráren. Užitné vlasnosti sádry lze zlepšit přidáním vhodných přísad. Byly testovány některé možnosti zlepšení konzistence, zpracovatelnosti a pevnosti sádrového pojiva. Dále byla zkoušena zlepšení formulace pěnosádry (s nižší objemovou hmotností, s lepšími tepelně izolačními vlasnostmi). Byly zkoušeny tyto přísady: plastifikátory, disperze a několik typů vláken. Jako napěňovací činidlo byla použita křída s kyselou složkou. Všechny přísad byly v práškové formě, která umožňuje formulaci suchých sádrových směsí. (cs)
